Location
The
FOC
F/96
aperture
location
has
remained
relatively
stable
over
the
last
5
months,
staying
within
0.2''
of
the
reference
position
according
to
data
taken
on
8
August
1996.
That
conclusion,
however,
was
based
on
reconstructed
FGS
data
since
only
one
guide
star
was
acquired
when
the
images
were
taken.
A
second
set
of
observations
were
taken
on
11
September
and
will
be
analyzed
in
order
to
confirm
the
results
from
